我正在尝试将.amr文件上传到服务器。我的代码如下：
private static void uploadRecording(byte[] data) {
byte[] response=null;
String currentFile = getFileName(); //the .amr file to upload
StringBuffer connectionStr=new StringBuffer("http://www.myserver/bb/upload.php");
connectionStr.append(getString());
PostFile req;
try {
req = new PostFile(connectionStr.toString(),
"uploadedfile", currentFile, "audio/AMR", data );
response = req.send(data);
} catch (Exception e) {
System.out.println("====Exception: "+e.getMessage());
}
System.out.println("Server Response : "+new String(response));
}
public class PostFile
{
static final String BOUNDARY = "----------V2ymHFg03ehbqgZCaKO6jy";
byte[] postBytes = null;
String url = null;
public PostFile(String url, String fileField, String fileName, String fileType, byte[] fileBytes) throws Exception
{
this.url = url;
String boundary = getBoundaryString();
String boundaryMessage = getBoundaryMessage(boundary, fileField, fileName, fileType);
String endBoundary = "\r\n--" + boundary + "--\r\n";
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bos.write(boundaryMessage.getBytes());
bos.write(fileBytes);
bos.write(endBoundary.getBytes());
this.postBytes = bos.toByteArray();
bos.close();
}
String getBoundaryString()
{
return BOUNDARY;
}
String getBoundaryMessage(String boundary, String fileField, String fileName, String fileType)
{
StringBuffer res = new StringBuffer("--").append(boundary).append("\r\n");
res.append("Content-Disposition: form-data; name=\"").append(fileField).append("\"; filename=\"").append(fileName).append("\"\r\n")
.append("Content-Type: ").append(fileType).append("\r\n\r\n");
return res.toString();
}
public byte[] send(byte[] fileBytes) throws Exception
{
HttpConnection hc = null;
InputStream is = null;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
byte[] res = null;
try
{
hc = (HttpConnection) Connector.open(url);
hc.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + getBoundaryString());
hc.setRequestMethod(HttpConnection.POST);
hc.setRequestProperty(HttpProtocolConstants.HEADER_ACCEPT_CHARSET,
"ISO-8859-1,utf-8;q=0.7,*;q=0.7");
hc.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_LENGTH ,Integer.toString(fileBytes.length));
OutputStream dout = hc.openOutputStream();
dout.write(postBytes);
dout.close();
int ch;
is = hc.openInputStream(); // <<< EXCEPTION HERE!!!
if(hc.getResponseCode()== HttpConnection.HTTP_OK)
{
while ((ch = is.read()) != -1)
{
bos.write(ch);
}
res = bos.toByteArray();
System.out.println("res loaded..");
}
else {
System.out.println("Unexpected response code: " + hc.getResponseCode());
hc.close();
return null;
}
}
catch(IOException e)
{
System.out.println("====IOException : "+e.getMessage());
}
catch(Exception e1)
{
e1.printStackTrace();
System.out.println("====Exception : "+e1.getMessage());
}
finally
{
try
{
if(bos != null)
bos.close();
if(is != null)
is.close();
if(hc != null)
hc.close();
}
catch(Exception e2)
{
System.out.println("====Exception : "+e2.getMessage());
}
}
return res;
}
}
上面突出显示的是抛出异常的代码行：未连接。 有人可以告诉我可以做些什么来纠正这个问题？非常感谢。
更新：
